Forensic diatomology plays an important role in solving mysteries of drowning cases. The diatomology contributes significantly not only in determining the mode of death but also in determining the site of drowning. Presence of sufficient number of diatoms in vital distant body organs can establish ante-mortem drowning up to a certain extent. Question about the exact site of drowning is mostly raised particularly when circumstantial evidences are not clear about the drowning site or drowning site itself is not there. Distribution of diatoms in any water body, and their correlation with the diatom species recovered from the drowned body can be a method of choice to resolve the questions related to drowning site. Analysis was undertaken in order to record the significant variation in diatom diversity in the 10 (selected) different types of water bodies in Punjab (India) during different seasons (summer, autumn, winter and spring). This comparative study was conducted for two years. The data so obtained has been utilized to generate Diatomological Maps, which can be helpful in diagnosing the suspected drowning cases occurring in a particular area and characterization of different water bodies.
法医硅藻学在解决溺水案件谜团方面发挥着重要作用。硅藻学不仅在确定死亡方式方面，而且在确定溺水地点方面都做出了重大贡献。在重要的远处身体器官中存在足够数量的硅藻，在一定程度上可以确定生前溺水。特别是当关于溺水地点的间接证据不明确或溺水地点本身不存在时，关于确切溺水地点的问题大多会被提出。硅藻在任何水体中的分布，以及它们与从溺水尸体中 recovered （此处原文“recovered”有误，推测可能是“retrieved”，译为“获取”）的硅藻种类的相关性，可能是解决与溺水地点相关问题的一种首选方法。为了记录印度旁遮普邦10种（选定的）不同类型水体在不同季节（夏季、秋季、冬季和春季）硅藻多样性的显著变化，进行了分析。这项比较研究进行了两年。如此获得的数据已被用于生成硅藻学地图，这有助于诊断在特定区域发生的疑似溺水案件以及对不同水体进行特征描述。
